Large Format Digital Photography

Your justification there seems to be based on the idea that Bayer filters imply interpolation that disappears when you use 2x2 pixel blocks as single pixels... but that's wrong.

I believe I read your research a while ago. Thanks! Indeed, after I read some about these constraints (it might have even been your paper!) I did some tests and, though only casually scientific, proved to me that there was more resolution than I could get using state-of-the-art digital cameras. I've posted some of those comparisons. Like here

Perhaps one does need 16 pixels for every 1 good pixel.  I have no idea.  But I certainly believe there are limitations.  Anyway, at that point I decided whatever the limitations, two facts remained 1) there was increased resolution from the Digitiler and 2) I was getting that large format look I love.

My goal is to create camera for me, and any other large format photographers who are interested, to have a digital option that provides near the same feel as large format film.

In other words, my explanation is only meant to explain why someone might see that large format look.  I don't mean it to stand on its own.   In my experience, it's difficult to get into this stuff without being trolled.

You might get a kick out of my Large Format Digitalpage, which has a not-too-different discussion. I last updated it in 2013, so maybe it's getting to be time for me to say some more there...?

I'd be thrilled if you get into this stuff again!  I'm always open to talking about this stuff!

Incidentally, there is always LargeSense -- who market 4x5 and even 8x10 single-shot digital backs. However, they go the other direction, using very few, but very large, pixels. Then again, most of what they're doing is still B&W....

Did I forget to mention i don't have $100,000 lying around? HA HA.  I do mention LargeSense when I can.  I'd say we're both trying to do the same thing.  Obviously, if money is no object a LargeSense camera can do so much more than my thing because it doesn't take them 30 seconds to take multiple images.
